说明：  SAR雷达模拟的PPT，讲述SAR雷达回波模拟的具体原理，实现方法，和仿真结果(SAR)

DigiPic 函数主要功能是将一个图片形式的表格函数,获取其数据,拟合为一个解析式. 便于计算机使用 DigiPic功能描述 在matlab 2013a运行环境下,启动DigiPic 首先,导入要分析的图表照片 取点建立坐标系,坐标系在取点时同时输入对应的实际坐标值, 拖拽坐标点使其位置在图片上尽量准确,便于后面坐标的自动计算. 按右键完成坐标系的建立. 在图片上原函数图线处取点.同时自动计算函数值 在拟合页,导入函数数据.选择相应的拟合函数.自动计算出最佳参数. 在拟合前,可人工在函数列表中修改,设定参赛,使计算更快. 选择保存目录,保存数据.数据以excel文件保存,图片和数据文件最好放在一个目录里. excel文件数据可直接在其它分析软件中使用. 打开原分析文件时,可同时打开多个.( DigiPic function main function is to form an image in the form of a function, to get their data, fitting of an analytical style. To facilitate computer use DigiPic Description operating environment in matlab 2013a, start DigiPic First, import to be analyzed Charts Photos access point to establish a coordinate system, the coordinate system at the access point simultaneously enter the actual coordinate values ​ ​ corresponding to the coordinates of the point drag on the image to make it as accurate as possible location, easy to automatically calculate the coordinates back. completed by the right coordinates established. Uehara function graph in the picture at the access point. while automatically calculated in the fitting function value page data import function. choose the appropriate fitting function. automatically calculate the optimal parameters. before fitting, artificial modification in the function list, set the entry to make computing faster. choose to save)

MATLAB uses column-oriented analysis for multivariate statistical data. Each column in a data set represents a variable and each row an observation.

泥沙粒度参数计算程序,应用作图法来计算粒度参数，计算公式为国家海洋调查规范所用的公式，一共输出五个参数，平均粒径，中值粒径，分选系数，偏态系数，峰态系数。(Sediment grain size calculation procedures, the application of mapping method to calculate the size parameters, calculated as the National Marine survey specifications used in the formula, total output of five parameters, the average particle size, median diameter, sorting coefficient, skewness factor, kurtosis coefficient.)

This package contains the code for the Enhanced Local Subspace Affinity (ELSA) with Enhanced Model Selection (EMS+) and number of motions estimation based on the eigenvalue spectrum of the Symmetric Normalized Laplacian matrix.

逆变器的调制方法有多种，如单极性调制，双极性调制，单极倍频调制等，此处是单极性调制，并给出单极性调制发生器(There are many modulation methods for inverters, such as unipolar modulation, bipolar modulation, unipolar frequency modulation, etc. This is unipolar modulation, and a unipolar modulation generator is given)

采用极坐标，可计算网络潮流，格式和附件中ieee14.xls中数据格式是一样的，且潮流程序是通用的。(Using polar coordinates, you can calculate the network flow, the format and the ieee14.xls data format in the annex is the same, and the flow program is common.)
